To all whom it may concern Be itknown that 1, Tmaononn NAUs, a,

citizen of theUnited States, and resident of Milwaukee, in the county ofMilwaukee and State of -W1sconsin,-'have invented certain new and usefulImprovements in'- Tire- "effective two part wheel. rim for tires,thesainebeing especially adapted for use in connection with the clenchertype of tire.v

Specific" objects of my invention are to provide means whereby a onepiece stand- .ardrim may be converted into a two-part quickdemountableji rim without removing the rim body; to provide a metallictread band member having one edgeformed with a clencher 'bead and itsopposite edge formed with an annularly shouldered tongue for engagementwiththe contemporary shouldered edge of a clencher ring member; I

Heretofore wheel rims especially designed forthe cheaper grade'ofvehicles have been made in one piece comprising a tread band havingupturned beaded edges, which band portion is affixed to, the wheelfelly. To attach a resilient tire torims of the above mentioned type itis necessary-to spring the beaded edges of the tire over" thecorresponding beaded edges of the rim befor the assemblage "is effectedand this operation; is not only exceedingly tedious and annoy ing, butrequires the skill and strength to manipulate the parts and, in manyinstances, after such assemblage where an inner tube is used, ithas'been found that said inner tubes are pinched and conse-= quentlyvitally injured. The same objectionable features have been found toexist in the more expensive three part demountable rims, which latterrims require special tools for manipulating the same.

My,invention is designed to overcome all of the objectionable featuresmentioned by forming the rimintwo parts as hereinafter shown anddescribed, whereby a Enco ntable beaded ,ring is provided having a slipjoint connection with one edge of a tread band, the opposite edge beingprovided with d bead. Hence the tire may be slipped upon the tread-bandwithout ex- Specification of Letters Patent.

v panding the same and thereafter the removablering is pushed into placeto efiect a slip oint union with the rim band, said jo nt being effectedby a simple movement without straining, whereby these parts areperfectly nested to form an uninterrupted smooth tread surface. Thebeaded ring member and the'beaded tire band "member are then clampedtogether by a series of companion clips, which clips are confined bybolts preferably passed through apertures in the wheel felly. By thisbolting connectionbetween the companion clips the double chpsor cleatsdraw the separable members tightly together to form "a practicallysealed joint andthere is no'consequent strain upon the felly should saidfolly be of the wood type and, as a matter of 'fact,'the bolts server toadd strength to the felly, whereby the-latterisheldfrom bulging orsplitting transversely; WV ith the above and other minor objects in viewthe invention consists in certain peculiarities of construction andcombination of parts as set forth hereinafter with reference to theaccompanying drawings and subsequently claimed.

In the drawings Figure 1 re resents, a

equipped with a clencher rim embodying the features of my invention, thesection being indicated by line 22 of Fig. 2, and Fig. 2, a face view ofthe same with parts broken away and in section to more clearly illustrate details of construction. a hReferring-b y characterst0-the"drawings, 1 represents a wood felly having spokes 1' extendingtherethrough, and secured to the face of the folly is a tread band 2having an upturned annularly beaded edge 2 of the clencher type, thetreadband being secuTrid e opposite edge of the tread-band projectsslightly over the felly and is formed with an annular tongue-4, whichtongue is pro 100 vided with a slightly beveled upper face l, the saidupper face merging into a shoulder a. Thus the tongue is approximatelyonehalf the thickness 'of the tire tread. This tongue is formedresponding overlapping tongue 5, which tongue is formed at the base edgeof a clencher ring 6, the same being a companion of and corresponds tothe bead 2 of the tread band. The tongue 5, in connection 110 a wheelfor engagement with a corj with the base of the clencher ring, in everyrespect is similar to the tongue 4 with the exception that it is ofgreater diameter. whereby its inner beveled base-5' isadapted 5 to matchthe outer beveled face 4' of the tread tongue. The'ring tongue 5 isprovided with a shoulder 5", which shoulder is adapt- I ed to abut theouter edge of the tongue 4.

j whereby the companion tongues form a rab- 1O bet joint. In order thata standard rim may be converted into a two, part rim such as described,said standard rim, while upon the wheel felly, can readily be subjectedtoa cutting operation to remove one of the clencher beads and, aftersuch removal, the tongue 4 is formed by effecting a counter; sunk cut toform the shoulder 4 and upper face 4. Afterthis operation a removableflange which is made standard having a 20 tongue 5, is fitted to thetread band, as shown in Fig. 1. In order to bind the two parts of therim'firmly together, I provide com-- panion clips 7, any number of setsof which may befitted about the rim having concavoclencher beads. Thebase 7 of each clip is adapted to abut the side faces of the felly 1 andsaid base in each instance is apertured for the reception of a threadedclamping bolt- 8. The olts are passed through transverse channels 8,whichchannels are preferably slightly smaller than the bolts, wherebysaid bolts are screwed into place through the wood to thus insure moreperfect union es bolt head and hence after the 'bolt has been passedthrough the folly it can be driven home in such manner that its headwill effect socket engagement with the clip referred to, whereby thebolt is held against twisting when the nut 9 is given a final turn tocause the wings of the clips to firmly draw the beaded rim memberstogether, whereby the convexed wings which conform to thefor thereception of a correspondingly faced rabbet joint between said membersis closed up and, in effect the rim member now be- 3 comes a unit.

It is obvious, owing to the fact that the is produced between thecontacting lower end of the'clip base and the wood felly, whereb theupper clamping wings of the clips will tend to draw the beaded edges ofthe rim toward each other and exert a slight downward pressure thereon.

Attention is called to the open felly channels 8 for forming seats forthe clamping bolts, whereby said bolts are positioned to abut'the underside of the tread band,by means of which band they are thus confined inone direction. This construction also renders it possible to positionthebolts in 'uxtaposition to the clamping wings, wherey the drawingeflicienc is increased, the fulcrum oints upon w ich the clips arerocked being 'at a considerable distance below the bolts.

I claim: v c,

.The combination of a wheel having a felly, a flat tread band of uniformthickness permanently secured to the folly, the tread band terminatingwith a clencher bead at one edge and an annular shouldered tongue at itsopposite edge that projects for the most part beyond the juxtaposed sideof said felly, the upper face of said tongue beinginwardly beveled, aremovable clencher ring of a thickness corresponding to the thickness ofthe tread having an inwardly extended base edge formed with a companionannular tongue having anoutwardly beveled lower face for overlappingengagement with the corres ending beveled face of the tread band ton e,and means for clamping the removable clencher rings to said tread band.

In testimony that I claim the foregoing I have hereunto set my 'hand atMilwaukee Wisconsin in the presence of two witnesses.
